Our range of V-Pulleys are a tried and tested solution for a wide range of drives. Taper bore versions are offered from stock with a varying number of groves. By offering taper bored sprockets to suit standard taper bushes, several shaft diameters can be accommodated by a single pulley without the need for further machining. For low torque drives, it is also possible to use the taper bushes to clamp the V-Pulley on to the shaft without the need to use a keyway and key.

For special requirements (such as combining two belt profiles onto a single pulley) or large dimeter V-Pulleys up to 2400mm, please get in contact with us to discuss your specifications. If a standard taper lock bush fixing solution or cast iron material is not suitable for your application, then V-Pulleys can be manufactured to order with a range of bore options and material specifications.

To complement our wide range of belts, we also manufacture and supply a range of standard and bespoke pulleys for our V belts and Timing belts.
